About This Assessment
TORRENT computed debris flow hazard for the Waterfall Fire fire using physics-based models on real USGS 3DEP terrain data (10m resolution). The analysis covers 29 sub-watersheds across 4 design storm scenarios (2-yr, 10-yr, 25-yr, 100-yr return periods) using USGS logistic regression (Staley et al. 2017) for probability and Gartner et al. (2014) for volume estimation.
